treated to remove these defects as it from the coil for use. invention,the strapping is withdrawn According to the present The invention isillustrated by Way of example in the accompanying drawing in which Fig.1 is a perspective View showing the device according to the inventionapplied to a frame carrying a coil of metal band.

`g. 2 is a perspective view of the device on a larger scale,

Fig. 3 is a larger scale,

Fig. 4 is a sectional end elevation showing the method of mounting theroller Fig'. 5 is an enlarged sectional view of a part of plan View ofthe device also on a formed of a pair of metal strips between which thecoil is inserted. A strut 4 and fixing plates 5 are provided whereby theframe may be xedly mounted in a desired position.

mounted two hardened metal wheels or rollers lIJ each provided with adeep narrow groove l I on its periphery. The position of these rollers I0 is such that the grooves I I embrace the opposite edges of the band orstrapping l', said band beingI drawn between the two rollers l0 as it isdrawn 01T the coil I for use.

The rollers I0 are mounted toA rotate freely on pins I2 which vin turnare mounted with the requisite amount of longitudinal play in`longitudinal slots I3 in transverse member 9 and the ends of the pins I2are strongly drawn together by means of spiral springs I4 so that theslotted rollers I0 bear with considerable pressure upon .the edges ofthe band I and as the band is drawn the coil l diminishes, the band orstrapping engaging rollers I0 drop approximately towards the centre ofthe coil. In this way, the Whole of the band can be drawn though therollers I0 without any diliculty, and without a kink or inconvenientbend being formed in the band.

an inch more than the thickness of the metal band or strapping beingoperated on.

The entrance band when lying between said rollers.

2. Device for smoothing the edges of metal band, comprising a pair ofperipherally grooved rollers, means adapted to support said rollers forrotation about their own axes and also for movement to change the planeof rotation of said rollers, the peripheral grooves of said rollersbeing adapted respectively to embrace the opposite edges of a metal bandand to accommodate themselves to changes in the position of the bandrelatively to the support, and resilient means adapted to urge therollers into engagement with a metal band when lying between saidrollers.

3. Device for treating the edges of metal band comprising a pair ofperipherally grooved rollers, a pair of spindles lying parallel to oneanother upon which said rollers can freely rotate, means supporting saidspindles and permitting a limited movement of said spindles towards andaway from one another and also a movement about an axis at right anglesto said spindles, and spring means adapted to urge said spindles towardsone another.

4. Device for treating the edges of metal band comprising a pair ofperipherally grooved rollers, a pair of spindles lying parallel to oneanother upon which said rollers are mounted, means adapted to urge saidspindles towards one another, means supporting said spindles andpermitting a limited movement of said spindles towards and away from oneanother and a frame in which said spindle supporting means is mounted soas to be capable of rocking about an axis at right angles to saidspindles and parallel to a line joining said spindles.

5. A device for smoothing the edges of metal band, comprising a pair ofperipherally grooved rollers, means adapted to support said rollers forrotation about their own axes and also for movement to change the planeof rotation of said rollers, the peripheral grooves oi said rollersbeing adapted respectively to embrace the opposite edges of a metal bandand to accommodate themselves to changes in the position of the bandrelatively to the support and means adapted to urge the rollers intoengagement, with a metal band when lying between said rollers, a coilholder adapted to allow a coil of metal band to rotate as the metal bandis withdrawn and also adapted to carry the supporting means for therollers.

6. A device for smoothing the edges of metal band comprising a coilholder adapted to allow a coil of metal band to rotate as the metal bandis withdrawn, a pair of peripherally grooved rollers, the grooves inwhich are adapted to respectively embrace the opposite edges of a metalband, a support for the peripherally grooved rollers pivotally connectedto the coil holder and adapted to permit rotation of the peripherallygrooved rollers about their own axes and also to enable said rollers todrop approximately towards the centre of the coil in the coil holder asthe diameter of the coil diminishes and means adapted to urge therollers into engagement with a metal band when lying between saidrollers.

'7. Means whereby the edges of coiled metal strapping may be smoothed asthe strapping is withdrawn from its coil, comprising a coil supportadapted to allow a coil of. strapping to be rotatably mounted in saidsupport, edge smoothing members adapted to press upon the edges of thestrapping as it is withdrawn from the coil, and means movably connectingsaid edge smoothing members with said coil support in such manner thatthe edge smoothing members are free to move in the plane in which theoil support is adapted to hold the coil.
